As I understand it, permethrins have a very short life and only kill
on contact.  They supposedly leave little or nothing behind in the
way of a preventative.  You would have to continually treat the
items to prevent anything from happening. I do not know how long
they last, but I was told that after a few hours they are
ineffective.  That information may not be entirely accurate so I
would verify it with qualified pesticide operator.
